摘      要：Objective:To determine growth and reproduction biology of Philocheras trispinosus(***)with abundance of other caridean shrimps caught by beam trawl in the Southern Black ***:Samplings were carried out monthly with a beam trawl of 2 m length and 15 mm cod-end mesh size between December 2012 and November *** individuals were sampled between 1 and 40+m water depth from 146 ***:A total of 550 ***,618 Palaemon adspersus,12 Palaemon serratus,11 Philocheras fasciatus and 10 Crangon crangon were sampled during the study *** crangonid shrimps started appearing during the winter and spring and the number of individuals increased to reach their highest value in mid-winter and *** seasonal von Bertalanffy growth parameters for *** were estimated as L_(∞)=29.3 mm total length,K=0.860/year,t_(0)=–0.900 year,C=0.180,and t_(s)=*** start of the slow growth period was at the beginning of July(WP=0.510).Ovigerous females appeared in the sampling area between January and *** at sexual maturity was estimated as 25.69 mm total ***:The results supported the distribution and abundance of caridean shrimp species from the study area and the population dynamics of the most abundant shrimp species,*** current study can be answered as baseline data prior to management strategies to ensure sustainable conservation of the shrimp species.
